they introduced another atomic clock based on the element ytterbium that performs similarly to the strontium clock. “Exquisitely precise timing is built into every aspect of modern infrastructure,” NIST official Thomas O’Brian told the …
The new clock can beat the cesium clock, a type of atomic clock that an international body of experts has used to define the unit of one second. It is about 9.19 billion oscillations. The oscillations per second in the ytterbium clock approach …
To do this, they refined a technique central to atomic clock technology: the separated oscillatory field ... and repeat the process for a new excitation frequency. Thus, step by incremental step, they build up a chart of excitement probability …
As reported in Physical Review Letters, an experimental atomic ... ytterbium clock gives the time standards community more options in the ongoing development and comparisons of next-generation clocks, says NIST physicist Chris Oates, …
Researchers at the National Institute of Standards and Technology have invented the world's most precise atomic clock, according to a recently-published study in Science. The new clock, referred to as a ytterbium optical lattice clock, can …
Atomic clocks built at the official U.S. timekeeping laboratory tick with record-breaking regularity, scientists said — marking an advance that may someday allow researchers to perform new tests of ... the record-setting ytterbium clocks …
Another check involves comparing the ticking of different types of atomic clocks. The NIST scientists and colleagues at JILA, a research institute down the road in Boulder, are doing just that, comparing the ytterbium ... agree on a new …
Both time crystals rely on a quantum property called spin, which makes some atomic nuclei ... are so new that scientists still aren’t sure what materials time …
The new clock is based on strontium atoms ... The stability of the strontium clock is similar to that of the ytterbium atomic clock unveiled by NIST investigators back in August 2013. All atomic clocks need to undergo a process called …
WASHINGTON: Scientists claim to have developed a new record-breaking ... The strontium clock's stability - the extent to which each tick matches the duration of every other tick - is about the same as NIST's ytterbium atomic clock. Stability …
